An electrolyte composition can be capable of becoming molten when heated sufficiently. The electrolyte can include at least one lithium halide salt; and at least one lithium non-halide salt combined with the at least one lithium halide salt so as to form an electrolyte composition capable of becoming molten when above a melting point about 350&#xb0; C. A lithium halide salt includes a halide selected from F and Cl. A first lithium non-halide salt can be selected from the group consisting of LiVO, LiSO, LiNO, and LiMoO. A thermal battery can include the electrolyte composition, such as in the cathode, anode, and/or separator region therebetween. The battery can discharge electricity by having the electrolyte composition at a temperature so as to be a molten electrolyte.

Thermal battery electrolyte materials

A thermal battery can include: an anode of lithium alloy; a metal-fluoride cathode having Ni; and an electrolyte composition in contact with the anode and cathode. A thermal battery can also include: an anode of lithium alloy; a metal-fluoride cathode having an oxide selected from VOor LiVO; and an electrolyte composition in contact with the anode and cathode. In one aspect, a metal of the metal fluoride cathode includes Ni, Fe, V, Cr, Mn, Co, or mixture thereof. In one aspect, the metal-fluoride cathode includes NiF, FeF, VF, CrF, MnF, CoF, or a mixture thereof. A method of providing electricity can include: providing an electronic device having a thermal battery with a metal-fluoride cathode having Ni and/or having an oxide selected from VOor LiVO; and discharging the thermal battery to provide electricity.
